help with breed identification

[jcskowronek]

my silkie hen hatched three chicks a few weeks ago. i have a silkie rooster and some rir hens in the same flock. i think the silkie incubated a few rir eggs as well as her own. I'm wondering if anyone can help me to try to identify the breed of the chicks. i have attached the best pictures i have so far. they are about 5 weeks old

also,
does the foot color have anything tp do with the breed? like can that help to determine the breed?

Those are rir x silke.

Never seen one. Yours are the first I've seen. I showed them to my wife, she has mixed feelings. I on the other hand think they look really cool.
